1, the effect is better. The circular suction port design is closer to the source of oil smoke, and the smoking effect is better. Not limited by space, you can hang on the wall and not meet. Automatic opening and closing has good smoke collection effect, but its volume is huge, and the smoking effect is not as good as that of circular suction type.

2, the use time is long. The automatic opening and closing of the range hood is closely related to the cleaning and maintenance of the range hood, and long-term use will lead to failure. The circular range hood is not easy to be contaminated with too much oil, easy to clean and can be used for a long time.
